The world’s largest rocket successfully entered orbit for the first time—a milestone for SpaceX and a relief for future NASA moon missions
A beautifully preserved fossil from Mongolia’s Gobi Desert has solved a mystery that puzzled paleontologists for nearly 40 years. Tamirkhan balcarceli shows that zhelestids were not early relatives of modern placental mammals, despite having teeth that seemed to suggest they were. Instead, the rabbit-like animal belonged to a separate lineage of small Cretaceous mammals.
JWST has revealed that young planetary systems lose their planet-building gas through a changing mix of powerful jets, molecular winds, and radiation-driven outflows. As the disks age and their gas disappears, giant planets face a shrinking window to build massive atmospheres.
Millions of Americans are diagnosed with common conditions like cancer and diabetes — but some 10% of the population live with rare diseases that doctors often struggle to diagnose. On average, those with rare diseases will spend five to seven years searching for answers and see 12 specialists before they arrive at a diagnosis.In the process, they may be subject to incorrect, ineffective or even harmful treatments."Any medicine that you prescribe has a one-third chance of working, a one-third chance of doing nothing, and a one-third chance of hurting you," said Dr. Ada Hamosh, a geneticist and the center director for the Johns Hopkins Medicine-Kennedy Krieger Institute National Organization ...
Bones from extinct elephant-like creatures discovered along the shore of Lake Tagua Tagua in central Chile bear human-made cut marks and were found alongside stone tools, revealing that some of the first humans to live there were killing and eating these animals 13,000 years ago, new research shows. Archaeological excavations carried out over the past two years in the basin of the ancient lake revealed a large concentration of megafauna remains and stone tools, according to a Sept. 24 statement from the Catalan Institute for Human Palaeoecology and Social Evolution (IPHES-CERCA). Several bones from gomphotheres, an extinct group of tusked mammals related to modern elephants, displayed clear ...
A compound the body can make after eating pomegranates, walnuts, and some berries improved measures of heart function by up to 80% in animal models of a difficult-to-treat form of heart failure. Urolithin A helped stiff heart tissue relax and reduced scarring and abnormal enlargement. It also improved relaxation in engineered human heart tissue.
The Battersea Shield was pulled out of the River Thames in 1857. (Image credit: Universal History Archive/Universal Images Group via Getty Images)QUICK FACTSName: Battersea ShieldWhat it is: Bronze facing of a shieldWhere it is from: River Thames, LondonWhen it was made: Between 350 and 50 B.C.This masterpiece of ancient Celtic weaponry was discovered by a laborer who was working on a bridge over the River Thames in 1857. Named the Battersea Shield after the London neighborhood near where it was found, the bronze artifact shows no signs of use, leaving archaeologists wondering how it ended up at the bottom of the river.According to the British Museum, which acquired the shield directly from ...
After transplant, young hearts in both mice and humans showed signs of accelerated aging in older bodies, while older hearts in younger bodies seemed rejuvenated
From the smallest building blocks of life to prehistoric vomit and a newly discovered amoeba that can really take the heat.
Scientists resurrected antimicrobial peptides from mammals that lived millions of years ago and found that some were more potent against drug-resistant bacteria than modern human versions. These evolutionary relics could provide new clues for designing treatments as antibiotic resistance becomes an increasingly serious threat.
From the 13th to the 16th century, herring from the Sound—the strait in the Baltic Sea between Denmark and Sweden—was one of northern Europe's most important trade goods. Salted herring from the so-called Skanör-Falsterbo fishery fed large parts of Europe. Around 1570, however, the fishery collapsed rapidly, with far-reaching consequences for trade, politics and society. It took almost 400 years, until the 1950s, for catches to reach comparable levels again.
When light or sound bounces around inside an oddly shaped room, its reflections can quickly become difficult to predict. But new research led by scientists at the Advanced Science Research Center at the CUNY Graduate Center (CUNY ASRC) shows that waves can behave very differently when they travel through a special class of materials.
